Abstract
The utility model discloses a high-precision and high-strength output gear assembly of a seat rear elevation motor, which comprises an output gear part and a planet gear installation platform which are formed by cold piers and are coaxially connected into a whole, and is characterized by also comprising a fine blanking insert, wherein the planet gear installation platform is far away from the end surface of the end of the output gear part, and the cold pier is provided with a fine blanking insert installation cavity; and three planet gear shafts are precisely punched on the precisely punched insert. The beneficial effects of the utility model reside in that: the utility model has high strength and good stability; the precision of the part is high; and subsequent processing procedures are reduced.
Description
Technical Field
The utility model belongs to the motor gear field, concretely relates to raise high accuracy, high strength output gear subassembly of motor behind seat.
Background
referring to fig. 1, an output gear assembly 1 in a rear elevation motor currently used to elevate a seat includes an output gear part 2 and a planetary gear mounting platform 3. The output gear assembly 1 is formed by adopting a cold heading processing technology. Three planet gear shaft mounting holes 4 are cold-stamped on the planet gear mounting platform 3, and then an inner planet gear shaft (not shown in the figure) is embedded in each planet gear shaft mounting hole 4. The output gear assembly 1 has the advantages of multiple processing procedures, high cost and poor part tolerance stability. And the strength of the output gear assembly of the structure is low.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect of prior art, the utility model aims to provide a raise motor's high accuracy, high strength output gear subassembly behind seat.
In order to achieve the purpose of the invention, the technical scheme adopted by the utility model is as follows:
A high-precision and high-strength output gear assembly of a seat rear elevation motor comprises an output gear part and a planetary gear installation platform which are formed by cold upsetting and are coaxially connected into a whole, and is characterized by further comprising a fine blanking insert, wherein a fine blanking insert installation cavity is formed on the end face of one end, away from the output gear part, of the planetary gear installation platform in a cold upsetting mode, and the fine blanking insert is embedded in the fine blanking insert installation cavity in an interference fit mode; and three planet gear shafts are precisely punched on the precisely punched insert.
In a preferred embodiment of the present invention, the fine blanking insert mounting cavity is a circular fine blanking insert mounting cavity with a bottom, and three arc-shaped inner tooth sections are uniformly distributed around the circular fine blanking insert mounting cavity with the bottom; the fine blanking insert is a circular sheet type fine blanking insert, three arc-shaped outer tooth sections are uniformly distributed on the outer circumference of the circular sheet type fine blanking insert, and each arc-shaped outer tooth section is in interference engagement with the corresponding arc-shaped inner tooth section.
The beneficial effects of the utility model reside in that:
The utility model discloses a raise high accuracy, the high strength output gear subassembly of motor behind the seat adopt cold mound spare and the essence towards the technological means of a mutual combination, higher, the intensity stronger than prior art precision, long service life.
Drawings
Fig. 1 is a schematic structural view of a conventional output gear assembly.
Fig. 2 is the utility model discloses raise the motor behind the seat high accuracy, the decomposition sketch map of high strength output gear subassembly.
Fig. 3 is the utility model discloses raise the assembly schematic diagram of high accuracy, the high strength output gear subassembly of motor behind the seat.
Detailed Description
The invention is further described below with reference to the accompanying drawings and the detailed description.
Referring to fig. 2, there is shown a high precision, high strength output gear assembly 100 for a seat back lift motor comprising a cold heading formed and coaxially connected output gear section 110, a planetary gear mounting platform 120 and a fine blanking insert 200.
A fine blanking insert mounting cavity 122 is formed in the end face 121 of the planet gear mounting platform 120, which is far away from the output gear part 110, in a cold heading mode, the fine blanking insert mounting cavity 122 is a circular fine blanking insert mounting cavity with a bottom, and three arc-shaped inner tooth sections 123 are uniformly distributed on the periphery of the circular fine blanking insert mounting cavity with the bottom.
The fine blanking insert 200 is a circular sheet type fine blanking insert, three planetary gear shafts 220 are finely punched on the end surface 210 of the circular sheet type fine blanking insert, and the three planetary gear shafts 220 are uniformly distributed in the circumferential direction. Three arc-shaped outer tooth sections 230 are uniformly distributed on the outer circumference of the circular sheet type fine blanking insert.
The circular sheet type fine blanking insert is embedded in the circular fine blanking insert mounting cavity with the bottom in an interference fit mode, and each arc-shaped outer tooth section 230 on the circular sheet type fine blanking insert is in interference engagement with the arc-shaped inner tooth section 123 corresponding to the periphery of the circular fine blanking insert mounting cavity with the bottom.
To sum up, the utility model discloses an advantage includes:
The utility model discloses an output gear, cold-heading piece gear use with the interference fit of essence towards the piece, and the intensity of part is high, and stability is good.
